% Lexer for the ICU/CLDR Rule Based Number Formatting rule definitions.
% Step 1 is to read in the json rule set.
% Then for each ruleset, pass each rule to the parser in two parts:
% First the rule name
% THen the rule definition
%
% Can be invoked in elixir as:
%
% iex> :rbnf.string(rules_set_as_a_char_list)
